Analysis of photoemission data for hexamethyl phosphoric triamide was completed. The absolute yield versus photon energy was found similar to that of formamide despite the differences in chemical structure. The reflectance of Dow Corning 705 silicone oil in the VUV was redetermined by the double gas-ionization chamber technique from 10 to 27 eV. An energy loss function was compared with energy distributions of low energy scattered electrons from the oil surface. Optical studies were completed on the unsaturated molecule squalene in the 2 to 25 eV energy region. Values of electron and photon mean free paths were calculated for this molecule as well as the saturated molecule squalane. Values of yield were predicted for the 16 to 25 eV region from a theoretical model of photoemission. Near-normal incidence reflectance data published earlier on liquid water were reanalyzed to characterize beyond the 25 eV experimental limit optical parameters consistent with sum-rule constraints. Preliminary photoemission and reflectance measurements in the 16 to 25 eV range have been made on dielectric liquids representing chemicals containing different functional groups.
